Comments about Bosley Hair Thickening Fibers:

This product does a nice job of filling in thin spots. I was disappointed that the photo in the store showed an applicator that was not included in the box with the product but it seems to work fine just shaking it out without an applicator.

                My hair has gotten extremely thin due to my thyroid and I was feeling insecure about my appearance. This product not only covers well but also lifts my hair at the roots. I use it every day.

                      A:

                      We recommend choosing the shade that is most similar to your hair color for most natural looking results; for you, we suggest choosing Medium Brown.
